/*
 * For testing Qt Quick for Android (QQ4A) applications with QuickTest
 * Usage:
 *  QUICK_FOR_ANDROID_TEST_MAIN("test_name")
 *
 * This function does the same steps as the regular QtQuickTest macro, with one
 * exception: it does not parse tests from QML files. This is because in the
 * QQ4A context, the QML content is loaded by the hosting Android Activity,
 * via QtQuickView.java (QQuickView internally)
 *
 * So in order to execute tests, we need to just spin the event loop and wait
 * for the application to be manually quit by the tests. This is done via
 * QGuiApplication::exec(), which allows the QML to be loaded and the tests to
 * be run.
 *
 * Once there are no more testcases to run or the program has been aborted, we
 * continue the regular QtQuickTest routine, finishing up the QuickTestResult
 * logging and writing the Android exit code file, before returning out of the
 * function.
